I have seriously just lost it. I been doing water changes weekly, using redsea. And my alk n cal levels wont go down to normal levels. Cal is reading over 500ppm and alk is at 16. What can i do???? Its been a month and no change. Tank is a 32 gal long with zoas, a kenyan tree , leather and a mushroom. One clown fish, and one pipefish. Heater is at 79 degrees. Have 2 cartridge filters running all the time. If there is anymore info that could give me advice plz ask.
